Rogue Audio M-120 vs M-150

Hello;

I've had a pair of Rogue Audio Magnum M-120 amps for about 18 months now and drive them with a Rogue Audio Magnum 99 preamp. I've been extremely pleased with them, to say the least. Well I recently called Mark of Rogue Audio to order a new set of output tubes and he made me a great offer on upgrading my amps to the newer M-150's. Unfortunately there is no place near me where I can listen to the M-150's so if I upgrade it will have to be without hearing them first. Mark thinks I would be happy with the upgrade and he hasn't steered me wrong yet, but I was hoping to get some additional input before making a decision.

Mark tells me that the newer design produces far less heat, has about double the output tube life, and is more dynamic and transparent. Given how pleased I've been with my current amps I'm more than a little hesitant, but if I can take my system up a notch at a reasonable price, why not? Any input will be greatly appreciated.

Have a good day
Brad

I don't know how much power you need but, In triode mode, the amps don't start to clip until right around 100 watts

Yiroryos,
Many (myself included) have found VSR speakers to match very well with Rogue gear.

I'm using VR4's with the upgraded drivers. I can only comment on their match with the 120 Magnums, which is wonderful. I am looking forward to their return as 150's.

As a plus, Albert von Schweikert, like the Marks at Rogue, will answer emails, return your calls and is a gentleman.

HI KILLERPIGLET
THANKS ,I WILL LOOK INTO IT.
I WAS ALSO TOLD TO GO WITH VANDERSTEENS 3C OR MAGNEPANS 1.6 OR MEADOWLARK NIGHTHAWKS OR JOSEPH AUDIO RM25 OR PROAC'S 2,5
THE NIGHTHAWKS ARE KILLERS BUT THE PRICE IS STIFF ,LOVE VANDERSTEENS TOO. MOST LIKELY I WILL GO WITH USED.
BEST REGARDS

I just bought a pair of 150. These amps with stock tubes really makes my Manepan 20 top end sound very real without any harhness. I can now play Beatles,Abba,Beach Boys, and sit back enjoy until the end of time. Non harsh, Non glare, Non bright.
Very sweet like pure sex. Price tag is small.
